The extension spindles are made of corrosion-free materials and the centre sleeve and bottom cover protect against penetration of impurities. The design with break zone in key adaptor prevents damage of the valve.

- The top adaptor has a defrosting hole intended for insertion of a heating element to prevent freezing of ground water inside
- The two fixation lugs can be attached to AVK surface boxes and support tiles
- A lock spring prevents the telescopic part from collapsing during installation, as it creates friction inside the inner square tube
- The centre sleeve protects against penetration of impurities between the two outer PE pipes
- The inner tube is press fit to the key adaptor and bottom adaptor to safeguard the galvanization of the tube
- The bottom cover protects the valve spindle from sand and dirt and enables it to rotate freely
